Fuel consumption measurement up to 4000 L/h. DFM Marine – new flow meters by Technoton.




Technoton introduces new product line of fuel flow meters – DFM Marine, for measurements up to 4,000 L/h. DFM Marine fuel flow meter is designed for monitoring of real fuel consumption and working time of river and sea vessels, mining machinery, diesel gensets and other high-power machinery. New product line adopted the best features of smaller DFM fuel flow meters, but also became more precise and embodied advanced developments of Technoton.


Fuel flow meter DFM Marine 2000C



Origins of DFM Marine.


In DFM Marine fuel flow meters we implemented all features of “automotive” fuel flow meters DFM:

  • Wide measurement range, ensured by digital processing of calibration results;
  • Advanced functionality: fuel consumption and working time counters – total and in different engine working modes: “Idling”, “Optimal”, “Overload”;
  • Embedded battery and multifunctional electronic display;
  • Stand-alone (autonomous) version and version with signal cable (digital interface or pulse signal).
Special features of DFM Marine.
  • Identifies Events “Ignition ON/OFF”, “High/low supply voltage”, “Interference attempt”. Sends Events via S6/CAN-interface;
  • Additional resettable fuel consumption and working time counters;
  • Option to choose from two measurement units: metric or American.


DFM Marine is compatible with S6* technology and easily integrated with onboard telematics system together with DUT-E CAN fuel level sensors, FMSCrocodile and MastercCAN FMS-gateways.

* - S6 is a CAN (J1939)-compatible standard for data integration of standard onboard electronics of vessels, vehicles, tractors, diesel generators with DFM and DUT-E CAN.



Along with flagship S6/CAN-interface, DFM Marine is manufactured with normalized pulse signal, DUT-E Com (LLS) protocol over RS232 and Modbus protocol over RS485.



In contrast to DFM product line, DFM Marine fuel flow meters show data not in liters, but in cubic meters (or in gallons – depends on configuration).



Basic technical specifications.


Fuel consumption measurement range:

  • 20-1000 L/h – DFM Marine 1000
  • 40-2000 L/h – DFM Marine 2000
  • 80-4000 L/h – DFM Marine 4000

Measurement error – not more than 0.5%.

DFM Marine can be used with diesel fuel, mineral oil and other fluids, which has kinematic viscosity within 1.5-6 mm/sec2.

Measurement chamber of DFM Marine is made of corrosion-proof metal – brass. Body and thread/flange is made of either brass or duralumin.
